emp strike from sun maybe are not a bigger threat to our electrical system ( compared to emp strike from nuclear blast ). if our position are far-far away from city ( at least 30 km from nearest city ).
because if we take a look from “nuclear strike target” in probable nuclear war, the most target are in city and strategic military asset.
that’s why if we have bug out place / homestead, that located in remote country or in the middle of nowhere then big chance are our equipment are safe from emp nuclear strike.
